You must love the crust of the earth on which you dwell more than the sweet crust of any bread or cake. You must be able to extract nutriment out of a sand-heap. You must have so good an appetite as this, else you will live in vain
Henry David ThoreauAll health and success does me good, however far off and withdrawn it may appear; all disease and failure helps to make me sad anddoes me evil, however much sympathy it may have with me or I with it.
Henry David ThoreauIn an ancient and dead language, any recognition of living nature attracts us. These are such sentences as were written while grass grew and water ran. It is no small recommendation when a book will stand the test of mere unobstructed sunshine and daylight.
